从软件设计的角度,对变水层拖网渔船船型技术经济论证的一般模型与方法进行了抽象。选取合理的数据结构与程序框架,以Excel软件为基础,利用Visual Basic for Applications开发语言设计开发了适合于变水层拖网渔船船型技术经济论证的通用程序。实例计算表明,该通用程序在变水层拖网渔船船型技术经济论证分析方面具有较强的通用性和实用性;同时,由于其功能独立、输入输出数据通用,开发的程序可作为船舶CIMS 中的“渔船船型技术经济论证”子系统,以辅助渔船总体设计中的初期方案确定以及技术任务书的制定工作。
From the perspective of software design, a general model and methodology for technical and economical evaluation of hull form of large middle-water trawlers are researched. Reasonable data structure and application framework is selected and the universal program is developed with Visual Basic for Applications program language based on software MS-EXCEL. Good universality and practicability is shown through case study. Due to independence of functions and universality of input and output data, the developed program can be integrated into the system called as“technical and economical evaluation and optimization of hull form for fish vessel” in the ship CIMS and assists in making initial hull form plan and designing technical specification.
